i got new camera and it has a way to save pics in tiff but there hugeeeeeeeeeeee id guess like 100 megs per pic is it better then jpeg or other stuff|?
Yea, as jtice said, there is no need for you and tiff raggie. They are totally uncompressed pictures. I have taken some outstanding pictures with, shall I say our, camera ;-) I am ultra happy you got a new camera so you can take shots of lights and the like. And I still thank your for selling me your old one. I have gotten some INCREDIBLE pictures with it.
jtice, in a complex JPEG, you will see a lot of loss going from 1.2MB to 350KB. the point is that an 1024x768 pixel image compressed to 400KB will look VERY good on the screen and is a good amount of overkill for anything you will want to post. however...that same image, printed at say...600DPI, which is not much all things considred, will only be 1.28" x 1.7" in size when printed at good detail levels.
lesson: in print you can actually see a difference in higher resolutions because given a variable "dots per inch to print" you can control detail levels by taking high res images. on screen all that higher resolutions give you are very large pictures cause your screen will always display 72 DPI, or 96 DPI if you have one of those.
JPEG compression gives nasty artifacts, and considering a a very very low compression level will give you superb detail and almost no artifacts at 1024x768 and 400k. JPEG is the way to go, but overcompression to save space for something thats not being printed is a waste of time.
From what I've seen in most digital camera reviews, it's pretty difficult to discern much if any difference between tif and the highest quality jpg setting. Now if the the camera does RAW then that's a whole other ballgame as you have much more flexibility with after image processing.
I have found that if you keep losses down below 15% in JPG files I cannot tell the difference on most pictures and it drops size (bytes) down to about 1/5-1/10 the original. I have very few no JPG pictures, GIF is good for some pictures with text and animation in them but otherwise JPG is the best.
I usually use level 10 quality in Photoshop for compression. 12 being no compression, and 1 being "compress me till everything looks interlaced and as if it's behind a faceted shower glass"
usually drops the size up to 50% with practically no artifacts. Transparent to me anyways.
As geepondy sez, it's RAW that gives you a definite edge. If for nothing else, I use RAW whenever the lighting might be dodgy, because you can adjust white balance in RAW on the fly in the computer. With a JPG, you have to color correct and guess yer way thru it.
Still, getting only 100 pictures per 1GB card is a little disheartening, so be prepared to have a lot of memory if you consistently use RAW. Otherwise, shoot jpegs.
